. This invention relates a i ii iforciiig and supporting device adaptedfor use in construction and repair work, and liiafs fdr its piifiiaryobsurface of holes inwau earded/resonate and other building materials ih'buildihgs.

Another primary object of this irifvention is to hold and retain inplaee' the mater-inseminated inthe holes to repair the holes and to forma base for the materials and become a permanent part of the surfaceworked on.

Another object of this invention is to .provide an inexpensive device"which "can be easily 'pb'sitioned on the internal surface of a wall orthe like and which WiIFcIinga'nd clar'iip orito the internal surface ofthe wall -to form a base for plastering material used to fill in thehole-or'openmg.

A primary feature of this invention resides in the provision of aplurality ofperfOrated-metaI disks, joined together by suitablesecuringmeans, the disks being adapted to cover one another forinsertion in the holes, and after insertion, to spread out into extendedposition to be clamped securely on the internal surface of the wallopening or other type of opening so as to form a base for repairmaterial.

These and ancillary objects and other meritorious features are attainedby this invention, a preferred embodiment of which is set forth in thefollowing description and illustrated in the accompanying drawings,wherein:

Figure 1 is a fragmentary side elevational view of a wall, illustratingan opening therein, this invention being clamped on the internal surfaceof the wall in alignment with the opening for retaining the repairmaterial utilized to repair the opening;

Figure 2 is a vertical sectional view taken on the transverse plane ofline 2-2 of Figure 1;

Figure 3 is a cross sectional view of this invention, showing the disksin flush engagement with the others;

Figure 4 is a front elevational view of this invention, showing thedisks in covering alignment;

Figure 5 is a front elevational view of this invention, showing thedisks in open and extended position;

Figure 6 is a side elevational view;

Figure 7 is a view in perspective of the clamp provided to engage theexternal surface of the wall and to retain the disks in position on theinternal surface of the wall even with the hole; and

Figure 8 is a'transversesecnona1 view "through one "of the disks,illustrating "the "s'auc'er or oupshape of the disk's.

Referring now more particularly to the drawings, wherein similarcharacters 'of reference designates corresponding parts throughout, thisinvention, generally designated by"the-'character reference ID,comprises a plurality of circular metal-disks, 1:2, M-a'nd 16.coursefithe size and number of the disks is 't'o'be "determined byactual working"'c'onditions fans the "s'ize=off'the opening desired tobe repaired, with respect :to Figure 1 of the drawings. "ThedisKs-are-suitabIy perforated, as at l 8 in evenspacenfent*throughout,and are adapted to cover one another for insertio'n'i'n a holeOrbp'ening. For this-purpose, the disks are preferably formed with aconvex outer surface and a concave under surface, the disks beingsaucer-shaped. The disks are juxtaposed when inserted through the"openirig fand are adapted to be extendedbr'fanne'dout when positionedon the inner surface 'of th'e wall. The disks are preferably pivotedtogether 'off 'center by any suitable means, such as a bolt 20 and aconventional nut 22, the bolt being placed through the off-centeropenings or apertures l8 formed in the disks. For the purpose ofmaintaining at least two of the disks in juxtaposition, and establishingthe axially aligned position thereof an arm 40 is formed integrally withthe periphery of one of the disks, preferably the middle disk I2. Thearm is bent back upon itself and terminates in an end extension 42engageable with the upper surface of the disk l4. Of course, the arm 40may be secured by any means, such as welding or the like, to theperiphery of any of the disks and serve to engage and receive thecompanion disks and maintain the set of disks in juxtaposition.

Thus, with reference to Figure 1 of the drawings, the juxtapositioneddisks are inserted through the opening 30 in a wall 32, and afterinsertion the bolt 20 is twisted clockwise or counter-clockwise untilthe three disks fall into an extended position, as seen in Figure 1. Aclamp 24 comprising a medial body portion 26 having a central aperture28 therein is adapted to engage the external surface of the wall and tosupport the disks in an extended position on the internal surface of thewall in alignment with the opening. The clamp 24 has a pair of laterallyextending wings 34 and 36 which are spaced from the plane of the bodyportion 26 by means of forwardly extending parallel connecting portions38. The wings 34 and 36 are adapted to seat in rectangular grooves 48formed in the external surface of th wall, as seen in Figure 1 of thedrawings. Thus, the filler material placed in the opening and receivedby the disks will completely repair the opening and the material may bepositioned over the extending wings of the clamp, so that all of therepair structure is hidden from view, to avoid any marring of theappearance of the wall.

Of course, it is to be apparent that the disks can be made in all sizesand from all types of material, depending upon the size of the openingand the type of repair material to be utilized. For example, inrepairing an opening in an automobile or metal body, the disks can befashioned as shown in Figure 8, wherein the disks are formed from asubstantially imperforate piece of material, having a single aperture l8formed therein. The single aperture 18 in each disk is adapted toregister with the other apertures and to receive suitable securingmeans. It is to;be noted that the single aperture I8 is disposed asubstantial distance from the center point'of the .disks.

Thus, it can be seen that the base forming disks, in association withthe anchoring and locking member 24,- serve as a base for supportingrepair and lining material. The anchoring of the disks to the internalsurface of the wall can be easily performed .and the placement of thedisks in alignment with the opening furnishes an extremely effectivemeans for holding building or repair material in place.

However, since many other purposes and objects of this invention willbecome apparent to those skilled in the art upon a perusal of theforegoing description in view of the accompanying drawings, it is to beunderstood that certain changes may be effected thereon as coming withinthe spirit of the invention and within the scope of the appended claims.

Having described the invention, what claimed as new is:

1. A device for backing repair material placed in a hole in a wallcomprising a series of perforated superposed disks, a nut equipped boltextending through said disks eccentrically thereof and pivotallysecuring the same together for relative swinging movement into axialalignment for passing through said hole, and out of axial alignment tooverlap one side of the wall around said hole, and a bar slidablymounted intermediate its ends on said bolt for movement axially thereofat one side of the series of disks for engagement with the other side ofsaid wall adjacent opposite sides of the hole, said series of disks andsaid bar being relatively adjustable laterally by tightening of saidbolt to clampingly engage the first and second-named sides of the wallrespectively.

2. A device according to claim 1, wherein said bar'is provided with endwings ofiset laterally therefrom toward the series of disks forcountersinking in grooves formed in said other side of REFERENCES CITEDThe following references are of record in-the file of this patent:
